Abstract: A system and method are provided for displaying video surveillance fields of view limitations. The system and method perform video surveillance of a given area and then geo-locate any obstacles within the area, including measuring their overall size and shape. The system and method map the size, location and shape of the objects into a database and then identify where there are video surveillance coverage gaps from each vantage point where video surveillance is being performed on the area. The system and method then determine where there are overlapping locations of blocked video surveillance (i.e., locations that are “invisible” to video surveillance). The system and method create a simulated image of the area from an orientation above the area which indentifies locations within the area that may not be seen by video surveillance from any of the vantage points where video surveillance is being performed.

Abstract: A method includes receiving a request from a mobile device to attach to a private wireless network, determining if a subscriber identifier is in a security database, determining if a mobile device equipment identifier is in the security database, authenticating the phone using the subscriber identifier and the mobile device equipment identifier, granting access to the private wireless network only if the phone is authenticated, and passing data between a computer system and a mobile device to monitor and control a remote monitoring and control system.

Abstract: The present Invention describes a method and system for calibrating, to an optimally ergonomic position, a surgical platform for use in laparoscopic surgeries. The bases of the method include the surgical site within a patient and the laparoscopic port placements within the ventral wall of the patient arranged in a three-dimensional coordinate system, and biometric data of the surgeon conducting the laparoscopic procedure.

Abstract: An antenna includes a plurality of loops and a plurality of double pole double throw (DPDT) switches. The plurality of DPDT switches is coupled to the plurality of loops. The DPDT switches are configured to cause a change in direction of current in one or more of the plurality of loops, thereby altering a direction of a magnetic field in one or more of the plurality of loops, such that a device positioned at a plurality of positions in relation to the antenna is electromagnetically coupled to the antenna at the plurality of positions.

Abstract: Some embodiments relate to a contactless RF coupling device that includes a first substrate and a second substrate. The RF coupling device may provide a broadband, low loss electrical connection without mechanical contact as would a conventional mechanical connector. The first substrate includes a first ground plane on one side and a first transmission line on an opposing side. The first transmission line includes an enlarged first coupling member at an end of the first transmission line. The second substrate includes a second ground plane on one side and a second transmission line on an opposing side. The second transmission line includes an enlarged second coupling member at an end of the second transmission line. The first ground plane may not extend under the first coupling member and the second ground plane may include an opening that is aligned with the second coupling member.

Abstract: A system for supplying hydrogen gas to a lighter-than-air (LTA) vehicle includes a manifold having multiple vessels. Each vessel has a first chamber that is separated from a second chamber by a barrier. A trigger assembly integrated with the barrier allows a liquid to be combined with a reactant and a catalyst in the second chamber to form a chemical reaction to generate hydrogen gas. A pressure relief valve located on each vessel opens to allow the hydrogen gas to exit when a predetermined pressure is reached, and the hydrogen gas is supplied to the LTA vehicle connected to the manifold.
